IEC 61196-6-2:20 20 RLV包含官方IEC国际标准及其红线版本。Redline版本不是官方文档，它只有英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61196-6-2:20 20适用于IEC 61196-6中描述的同轴通信电缆。它规定了75-4型有线电视分支电缆的要求。这些电缆用于有线电视分配系统、监视和控制系统、卫星电视接收系统以及双向混合光纤同轴电缆（HFC）。工作频率为5 MHz至3 000 MHz。本文件应与IEC 61196-1和IEC 61196Ï1/4Ÿ6结合使用。它决定了模型和类型的布局和样式。第二版取消并取代了2018年出版的第一版。与上一版相比，此版本包括以下重大技术变更: -变型的指定，包括构造细节 -一致的筛选类别， -仅对柔性电缆进行弯曲测试。

IEC 61196-6-2:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61196-6-2:2020 applies to coaxial communication cables described in IEC 61196-6. It specifies the requirements for 75-4 type CATV drop cables. These cables are used in CATV distribution systems, surveillance & control systems, satellite television receiving systems and as bidirectional hybrid fibre coaxes (HFC). The operating frequency is from 5 MHz to 3 000 MHz. This document is to be used in conjunction with IEC 61196-1 and IEC 61196？6. It determines the layout and style with respect to the model and type. This second edition cancels and replaces the first edition, published in 2018. This edition includes the following significant technical changes with respect to the previous edition:
- designation of variants including construction details
- consistent screening classes,
- bending test only for flexible cables.
